   of emissions, radiations, or inductions upon reception in a
   radiocommunication system, manifested by any performance degradation,
   misinterpretation, or loss of information which could be extracted in
   the absence of such unwanted energy.

   Licensee. A person that has been granted an individual license by the
   FCC.

   Mean power output. The average power supplied at the radio frequency
   output of a transmitter during a time interval of at least 0.1 seconds,
   taken under normal operating conditions.

   Mobile station. A station, intended to be used while in motion or
   during halts at unspecified locations, that communicates directly with
   base stations and other mobile stations, and with control stations and
   other mobile stations through repeater stations.

   Modulation. A process of altering the amplitude, frequency and/or phase
   of a radio frequency carrier wave generated within a Personal Radio
   Service transmitter, for the purpose of impressing onto the carrier
   wave information to be transmitted.

   Necessary bandwidth. For a given class of emission, the width of the
   frequency band which is just sufficient to ensure the transmission of
   information at the rate and with the quality required under specified
   conditions.

   Occupied bandwidth. For an emission, the width of a frequency band such
   that, below the lower and above the upper frequency limits, the mean
   powers emitted are each equal to 0.5% of the total mean power of the
   emission.

   One-way communications. Communications where information always flows
   in one pre-arranged direction through a communications channel.

   considered to be remote control.

   Repeater station. A station in a fixed location used to extend the
   communications range of mobile stations, hand-held portable units and
   control stations by receiving their signals on one channel (the input
   channel) and simultaneously retransmitting these signals on another
   channel (the output channel), typically with higher transmitting power
   from a favorable antenna location (typically high above the surrounding
   terrain).

   Spurious emissions. Unwanted emissions, the level of which may be
   reduced without affecting the corresponding transmission of
   information, including harmonic emissions, parasitic emissions,
   intermodulation products and frequency conversion products, but
   excluding out-of-band emissions.

   to an antenna, either directly or through a feedline.

   Transmitter type. A sample transmitter submitted for testing to

   § 2.908 of this chapter) and representative of all other transmitters of
   the same type.

   Two-way communications. Communications where information flows in both
   directions through a communications channel, either simultaneously
   (duplex operation) or alternately (simplex operation).

   necessary bandwidth; comprising out-of-band emissions and spurious
   emissions.

   User. Any person who uses or benefits from the operation of a Personal
   Radio Service station.

   Voice obscuring feature. A feature incorporated into a Personal Radio
   Service telephony transmitter that alters the sound of the user's voice
   in such a way that the communications are intended to be understandable
   only to individuals using a similar unit that reverses the process on
   the receiving end, so that the voice again becomes intelligible.
